- Ivo Hugh's Safari: A hippo from the zoo gets loose and wanders into the hills of the Skarloey Railway. Ivo Hugh must catch it, but he is quite scared of how ferocious it may be.
- Episode 36: The Fat Controller brings another member of Daisy's class on trail for the Ffarquar Branch Line, and history repeats itself.
Other ideas being considered are:
- A story involving an autistic character who has trouble fitting in.
- A story involving the Culdee Fell Engines

The following are confirmed
- Bill and Ben
- Annie and Clarabel

After Season 5
The fifth season will conclude at the end of 2018. T1E2H3 will conclude the Engines of Sodor here so he can focus on his film career. There will be several specials before a final in the summer of 2019. He will still be a member of the fandom, and may even turn to modeling characters as a hobby. However, in the future when he gets his own house, he may begin a new Thomas series, using something other than Trainz.
